This invention relates to new and useful improvements in an automatic slot machine for recording the human voice, music and other audible sounds on discs or other records h and films.

The invention has for an object the provision of a device of the classmentioned which is of simple durable construction, dependable in use and eflicient in action, and which can be manufactured and sold at a reasonable cost. y

The invention proposes a booth having a sound compartment and an apparatus compartment, a microphone supported in said sound compartment, and apparatus within said apparatus compartmentfor automatically recording from said microphone and u on conclusion ejecting the record throug a V chute to said sound compartment, upon the insertion of a coin through a slot in said sound compartment.

F or further comprehension of the invention, and ofthe objects and advantages tne're of, reference will be had tothe following enlarged detailed view of a portion of Fig. 2.

Fig. 5 is a View similar to Fig.2,but illu'strating a modification.

Fig. 6 is a fragmentary enlarged detailed view of a portion of Fig. 5. J I Fig. 7 is a horizontal sectional view taken on the line 7- 7 of Fig. 6.

Fig. 8 is a schematic wiring diagram of the device. a

The automatic slot machine comprises a booth lo having a sound compartment 11 and more par- Y an apparatus compartment 12, a microphone 13 supported in said sound compartment 11, and apparatus within said apparatus com-' partment 12 for automatically ,recording from said microphone and uponconclusion ejecting the record through a chute 14 to said sound compartment, upon the insertion of a coin through a slot 15 in said sound compartmeut. x y

The booth 10 is shown rectangular in plan view. It is provided with a vertical partition 16 for dividing it into the compartments 11 and 12. The sound compartment 11 is sound proof and of sufficient size so that one or more persons may be comfortable therein. It is provided with side doors 17 and a front window 18. The doors are shown formed with glass panels 19. A seat 20 is arranged within the sound compartment 11 so that a person may be comfortably seated.

This seat has a foot rest 21 at its bottom. The

apparatus compartment 12 is provided with several doors 22 for access to repair or take I care of the apparatus. The supporting of the microphone 13 is accomplished by a vertical wire 23 strung from the top to the bottom of the sound chamber 11, and the microphone should be frictionally engaged upon the vertical wire so that it may be manually moved to a'comfortable' height. The slot 15 connects with a coin chute 24 which discharges into a coin box 25. W

The apparatus within said compartment for automatically recording from saidmlc-rophone comprises a vacuum tube amplifier. 26

electrically connected with the microphone and with an electric recorder 27 These units may be of any conventional design and construction, generally known. A vacuum tube power unit 28 is shown connected with the amplifier and connected for receiving current from live leads 29. A coin control switch 30 is attached upon the chute 24 and has a finger 31 extending-into the coin chute for engage ment by apassing'coin. Both the vacuumtube amplifier and the vacuum tube power unit'are of the conventional type, and therefore not illustrated in the drawlngs.

The apparatus within the compartment 12 i also includes meansfor storing records. This means is shown to comprise three vertical screws indicated by reference numerals 32, 33

Two of the screws, namely 32 and 33, are rotatively supported at their tops by engaging in blocks 35 supported to the top of the coma finger 37 which is pivotally ed in the bottom of the screw partment 12. Brackets 36 rotativfely support the bottom ends of the screws 32 and 33 and are themselves supported upon he partition 12. The screw 34 is rotatively ounted upon 'ounted on a lug 38 projecting from the to of the booth. This pivotal mounting is such, that the screw 34 may be moved to a position as indicated by the dot and dash lines 39 in F 2. The bottom of the screw 34 is rotatively supported upon a bracket 40 attached on the booth 10. The bracket 40 is formed with a niche 41 receiving .a pointed plunger 42 slidably mount- 34 and normally urged outwards by an expansion sprin 43 housed within a cavity 44 in the bottom of the screw. The plunger 42 normally holds the screw in the vertical and whenever it is desired it may be manually moved u so that the screw may be swung to the horizontal as shown at 39. A plurality of records 45 are shown supported between the threads of the screws 32, 33 and 34. r

The apparatus within the compartment 12 also includes a means for positioning one rec- 'ord on a turn table 46 for coaction with the This means comprises of the screws 32,

electric recorder 27. gears 47 attached uponeach 33 and 34 and meshing with a master gear 48 upon a spindle ,rotatively mounted in the top of the booth 10 and supporting a sprocket wheel 49 en aged by a chain.-.50 extending over a secon sprocket wheel 51 fixed upon a shaft 52 which is rotatively supported by a standard 53 on the partition 16. A universal joint 54 connects the shaft 52 with another shaft 55 carrying a bevel gear 56 meshing with another bevel gear attachedmpon a shaft 57. This shaft is rotativel supported in a standard 58 attached on t e booth 10. A

worm wheel 59 is fixed upon the shaft 57 and meshes with a .worm pinion 60 on a shaft 61 of I an electric motor 62.

The apparatus within the compartment 12 also includes means for advancing the electric recorder 27 over the face of the record on the turntable 46 and upon conclusion automatically returning to initial position. This means comprises a stem 82 supporting the v turntable 46 and rotatively mounted in ,a

7 acam the turntable 46 106 connected with a shaft 107 carrying a standard 83 which is attached within the easing. The lower end of this stem rests upon 82 andin the normal recordingposition of mesheswith a train of gears bevel gear 108 meshing with a bevel gear 109 tached upon the partition is attached upon the extended end of the arm 69for normally urging 86. A gear 105 is fixed upon the stem' fixed upon a rotative mounted rod 110 having a threaded portion 111 threadedly engaging the said electric recorder 27. In a lowered position of the turntable 46, that is, when it discharges a finished record, the gear 105 meshes with a gear 112 of a gear speed increase system termlnatin 113 fixed upon the shaft 107. his latter gear system is 50 arranged ,that the rotations of the shaft 107 will be opposite to that had when the gear 105 meshes'with the system 106. During operation of the turntable 46 in its normal recording position, the electric recorder 27 slowly moves across its face and accomplishes recording. This slow motion is obtained through the drive mechanism which includes the gear 105 on the stem 82. When the cutout portion of the cam 86 is reached so that the stem is lowered, the gear 105 then engages gear 112 of the speed increase system The apparatus within the compartment 12 in the embodiment shown in Fig. 8 also in-" cludes a modified means for advancing the electric recorder 27 over the face of a record on the turn table 46 and upon conclusion automatically returning to. in'tial position. This means comprises a pinion 63 fixed uponthe shaft 52 and meshing with a gear 64 fixed upon a spindle 65 rotatively mounted through 1 the core of an electromagnet 66 which is at- 16. A collar 67 spindle 65 and is formed with radial teeth 68 upon its top face engaging complementary teeth in a radial arm 69 which supports the said electric recorder 27. A spring 70 is coaxially arranged on the spindle 65 and acts between the electromagnet 66 and the radial engagement with the teeth 68.

An arm 71 projects from the partition 16, and a spring urging the radial arm to a position in which the electric recorder 27 is off from the turn table 46. A switch pole 73 is slidabl mounted upon the arm 71 and has its ends 4 down turned and straddling the radial that upon reaching either end of its'stroke the radial arm moves the pole. The slidable mounting of the pole is accomplished by, screws 75 projecting from the pole 73 and en-' gagingthrough an arcuate slot 76 formed in the arm 71. One of the screws 75 constitutes a contact and is engageable against a contact finger 77 inone position'of the pole 73. The contact 77 is insulated from-the arm 71 by 72 is connected betweenthe" arm 71 arid the radial arm 69 for normall arm 69 so in a gear the teeth into I in parallel with the power leads 29. When the solenoid 66 is energized, it draws the radial arm 69 upwards so that the teeth of the radial arm disconnect with the teeth 68 of the collar 67.

The turn table46 is providedwith atop peg 81 engageable through a central opening in one of the records 45 and with a supporting stem 82 rotatively mounted in a standard 83 supported in the booth 10. A pinion 84 is fixed upon the stem 82 and meshes with a gear 85 on the shaft 61 of the motor 62.

A cam 86 is fixed upon the shaft 57 and en gages against the bottom of the stem 82 to hold the stem in various elevated positions. The cam has a portion coaxial with the shaft 57 which constitutes the normal recording positionof the stem 82, that is, the proper supporting of the stem so that the recorder 27 may engage the record upon the turn table. The cam also has a depressed or cutout portion so thatwhen this portion is reached the turn table is dropped for discharging the record as hereinafter explained, and the cam also has a raised portion for raising the stem 82 to lift the turn table up for receiving one of the records held by the storing means. The raised portion is not necessary and may be omitted.

The said chute 14 is inclined and terminates at its inner end in fingers encircling the turn table 46 so that when the turn table is lowered a record resting upon the turn table will be drop ed upon the chute and thus be discharged. he said coin switch comprises a standard 87 attached within a casmg which is attached on the chute 24. This standard pivotally supports at 88 a member 89,.which has 'an extension constituting the finger 31. A spring 90 acts between the member 89 and the standard 87 for normally urging the finger 31 into the coin chute. The member 89 supports a contact 91' engageable in a depressed condition of the member 89 as indicated by the dot and: dash lines 92 with a stationary contact 93.

in series in a circuit including the power leads 29, the electric motor 62 and the power unit 28. Another standard 94 is attached to the casing of the switch and pivotally supports at 95 a fin er 96 formed with an opening 97 for receiving the member 89 and holding the latter member in the position indicatedby the dot and dash lines 92. A spring 98 normally holds the finger 96 in its operative (35 position. An electro magnet 99 is located motor 62. The

The contacts 91 and 93 constitute a switch beneath the finger 96 so that upon being energized draws the finger to release the member 89. The electro magnet 99 is connected in series with a switch 100 arranged on the chute 14 and so constructed that when a rec- 'ord is discharged through the chute, this latter switch is momentarily'closed. The switch 100 and the electro magnet'99 is connected in parallel with the live leads 29.-

The operation of the device may be traced by assuming that no records 45 are supported upon the storing means, that the member 89 is free, that the stem 82 is in the depressed portion in the cam 86, and that the radial arm 69 is in a position off from the turn table. The first thing necessary is the engaging of records 45'within the holding means. This is accomplished by opening one of the doors 22 and pivoting the screw 34 to the dot and dash position 39. Then with a suitable holding jack records are placed against the screws and 33, and next the screw 34 is loweredto its vertical position so that the records 45 are properly clamped as shown in Fig. 2. In order to insure the correct positioning of the records, suitable guide cuts must be arranged upon the screws. Details of this are not necessary since it will be obvious to any person skilled in the art. v

The device is now in condition for operation. A person may now enter the booth through one of the doors 11, thendeposit the correct-coin through the coin slot 15. This coin passes through the chute 24 and discharges into the coin box 25. In passing through the chute it acts against the finger 31 so as to move the member 89 to the position indicated by the lines 92. This closes the switch 91, 93 and closes a circuitthrough the power supply 28 and through the electric power supply delivers power to the amplifier-26 and a person may talk recorder 27.

As the motor 62 operates, it transmits rotaits [through themircophone 13 for actuatingthe 4 i tions to the shaft 57. Rotations from this shaft are transmitted to the screws 32,33 and 34 which rotate so that all of the records 45 simultaneously move downwards. Rotation of the shaft 57 causes the cam 86 toturn and since the stem 82 was inthe extreme lowered portion of the cam it is .now raised to the ex treme elevated portion ,for positioning the turn table 46 immediately adjacent the lowest record 45.. By this time the lowest record is dropped by the rotating screws 34. Continued rotation of the shaft 57 lowers the stem 82 to the normal recording position of the cam 86. Rotations from the electric motor 62 are also transmitted to rotate the turn table 46. The turn table is now in its normal recording position and rotating.

The radial arm 69 was slowly moving into recording position and now is in recording position so that theelectric recorder 27 en-- arm into its initial or idle position.

, to the stem 65. and to the collar 67.

gages upon the record on the turn table. The radial arm 69 will continue in its slow travel across the surface of the record. A person within the booth may now talk and have his voice recorded on the record. Motion of the radial arm 69 is received from rotations from the shaft 52. These rotations are transmitted Since the collar 67 is directly coupled to the radial arm, it moves the radial arm'very slowly.

\Vhen the radial arm has reached theend of its recording position, that is, when the recorder 27 is at the inner position on the record, it moves the pole 73 so that the switch 75, 77 is closed. The spring 7 9 holds the pole 73 in its new position. \Vhen the switch just vmentioned is closed a circuit is closed through the electro magnet 66 which draws the radial arm 69 upwards against the downward action of the spring 70. Upon disengagement from the teeth 68, the spring 72 moves the radial In this position it acts against one of the downturned ends 74 of the pole 73 and moves the pole so that the switch connection I? 5, 77 is broken.- The spring 79 holds the pole 73 in this new position. \Vhen the switch '75, 77 is opened, the electro magnet 66 loses. its energy and spring 77 reengages the radial arm so that Y the teeth 68 are again engaged.

By this time the cam 86 has reached the position where the stem 82 drops into the lowered portion of the cam. Thus the turn table 46, is lowered and the record upon the turn-table discharged through the chute 14. As the record passes through the chute, it closes the switch 100 which momentarily energizes the electro magnet 99, moving the finger 96 to release the member 89 which is extended by the spring 90. The extension of the member 89 breaks the circuit at the poin";s

91, 93 so that the power is cut' from the power supply 28 and also from the electric motor 62. The device is now in its initial condition.
